The Pro:Motion Keyboard goes one step beyond regular ergonomic keyboards by incorporating motors that shift both angle and separation between keys throughout the day in order to prevent you from getting carpal tunnel syndrome.

There's a total of seven different "stations" that it cycles through, and only costs $130—not too horrible for a fancy keyboard. Seeing as regular ergo keyboards are proven to work at lessening the painful effects of typing too much, even if the motors don't work, you'll still have an ergo keyboard.
